Normalize CSS module naming: *Stories.module.css → *.stories.module.css

[Copilot]

Closes #

Standardizes CSS module file naming for Storybook stories. Previously, some story-related CSS modules used *Stories.module.css while others used *.stories.module.css. This inconsistency has been resolved in favor of the lowercase pattern.
